As you may have noticed from our front page Size Genetics is now the number one penis extender that we reviewed on this site. Back when we started out they were both about equal in how well they worked but X4 Labs was slightly cheaper. This has now changed thanks to a new design of Size Genetics.

They have changed the piece that attaches to the penis. This is by far the most important piece, too tight and it stops bloodflow to the penis head meaning it has to be removed while too slack means it doesn’t grip well enough when the penis is under any sort of traction which is needed for the gains.

The new design means that it works well for anyone, there are so many different ways it can be attached. This means it can be worn for longer periods and give better gains. You also get faster gains so all in all it is worth the extra few pounds. For this reason alone it has now gone to be the number one penis extender.
